Toko fixed inductor with low core noise

Toko Inc. rolled out a new fixed inductor designed for dc-dc converters in notebook PCs and other applications.

Measuring 13.6-by-12.4mm, the new FDU1250 features low core noise and a magnetically shielded construction low DC resistance. According to the company, magnetic iron powder has been used to combine high-current handling capability with compact size.

Capable of handling high current, the Pb-free new product has an inductance range between 0.5?H and 0.75?H, inductance tolerance of ±20 percent, DC resistance of 1.3 milliohms (max.) at 0.5?H, and rated current of 34A (max.) at 0.5?H. Maximum operating temperature is 125°C.
